This paper presents an integrated approach for implementing parametric life-cycle assessment in a project’s early phases, coupled with multi-objective design optimization, considering material cost and embodied carbon emissions. Life-cycle assessments are typically conducted at later stages in the design process, effectively limiting the range of optimization techniques available to be implemented. Parametric design presents an opportunity for embodied carbon reductions as it allows the evaluation of multiple design iterations in tandem with the optimization of various parameters such as material efficiency, shape, and frame. At the same time, with cost efficiency being an integral part of any project, coupling it with embodied carbon decisions, will help to solidify LCAs’ position at the early stages. The case study presented illustrates the benefits from implementing an LCA early on versus at later stages in a quantifiable manner.
